Methodology
CO₂ emissions computed from ADS-B flight data using aircraft-specific fuel-burn factors aligned with EUROCONTROL EMEP/EEA guidance. Distance figures derived from flight-trajectory data. EU ETS scope follows Directive 2003/87/EC as amended. Type rankings computed within the Gulfstream GIV population tracked by Carbon Sky Index.
